SPRING-MOTOR FOR TALKING-MACHINES.

ISpecicaton of Letters Patent. Patented NOV, 30,1915.'

Application filed September 24, 1914. Serial No. 863,277.

To all Iwhom t Concern Be it known that I, PLINY CATUCCI, a citizen of the United States, residing in the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Spring-Motors for Talking-h/Iachines, of which the following is a full, clear, and exact description, such as will enable others skilled'in the art to make and use the same. I

My invention relates to. spring`motors for talking machines of the disk typeaand has for its object the general improvement of the structure of such motors as wellas the speciiic improvement in a detachableonnection for-the spring barrel of such motors. It quite frequently happens, in the general and varied use to 'which talking machine motors are put, that the spring or springs within the spring barrel of the motor will break. llnder such conditions it is necessary toreturn the motor to the factory for repair. Again, the user of the talking machine may require the substitution of a longer spring. thereby permitting the motor itself, when wound up, to run longerthan it would. with the spring ordinarily placed within .the spring barrel. These and other conditions arise which make it necessary7 to remove the spring barrel from the motorY frame for repair, the substitution of another p spring barrel. or for any other possiblel purpose, andmy invention relates more specifically to the means by which the springloarrel and its contained spring may be removed from the motor frame without disturbing any of the other parts thereof.

In the accompanying drawings Figure 1, is a` bottom plan view of. my improved motor. Fig.4 2, is a top plan view of the same. Fig. 3, isa side elevation of the motor. Fig. .4, is an end elevation. Fig. 5, d, 7)., and c, are views respectively of one of the details in plan. sideuand end elevation. Fig. G, is :i detached side elevation of the main shaft bearing plate. g

v Similar reference numerals refer to like parts throughout the specification and drawings.

In order that a full understanding of the operation of the motor maybe had, I have given a complete' description of the same, although it is to be understood that in the main'the description is directed to the means for detachably supporting the springbar-.

lbottom plate 2, which'is of L-shape.

rel and main shaft. The motor frame consists of the top plate 1, of rectangular shape, provided with bearingapertures for the upper ends of the various gear shafts; and the The two plates 1 and 2, are secured together by means of the spacing studs 3, 4f and 5, in the usual manner. Extending upwardly 'from the bottom plate 2, is the bearing 6, provided with a suitable aperture to receive the main shaft hereinafter more fully described.

Looking at Fig. 2, upon the right hand end of the plate 1, will be seen' the detach- 1 able or pivoted bearing platev 7. This plate 7 is secured'to the upper face of the plate 1, by means of the two screws 8 and 9. 'lhe bearing plate 7 is provided with the downwardly extending bearing support 10,--apertured as at 11, in alinement with the corresponding aperture in the bearing 6, of the lower plate. The free edge -of'the plate 7 is provided with a downwardly extending strengthening flange 12, of triangular shape and provided at its widest portion with an aperture 13,7in vertical alinement with the corresponding aperture 14, in the bearing support 10.` The two apertures 13 and 14 are -designedlto form a bearing for the winding shaft 15.

The spring barre-ls 16, are of the type shown in my Patent No. 1,029,852, June 18th, 1912, wherein tandem springs are.

shown and described. The two spring barrels 16, are mounted Aupon the sectional shaft 17, u'pon which is also mounted a driving gear 18, said gear being rigidly connected to one -of the'spring barrels 16, and meshing with the first driven gear of the train. Upon the opposite end of the shaft and out.- side of the right hand spring barrel, is rigidly secured a second gear wheel 19. Upon the inner end of the winding shaft 15 is lo` l As above indicated, the bearing plate, with itssupport 10, for lthe main spring shaft1 7,islv secured te the upper-plate 1, by

.means of the screws"8` and 9. If, for any reason, it is desired toi remove the spring barrels v16,- and their shaft 17, from the frame of the machine, it is only necessary to remove the screw 9, when, of course, the

bearing plate 7 may be swung into the dotted line position asshown in Fig. 2, carrying with it the ,winding shaft 1 5 and gear 20, while -thel bearingaperture 'w11 is released from the lright hand end of the shaft 1'7 In this position the, spring barrel 16 may be readily moved from the other bearing 6 and' face of the upper plate l. The opposite end of the shaft 22 is. provided with the bevel gear24, .meshing with a similar gear 25, upon the vertical shaft 26; the latter shaft being carried in suitable bearings in the plates 1 and 2. Rigidly secured to the lower end of the shaft 26, is a comparatively large gear wheel 27 which engages a smaller gear 28, upon the mandrel shaft 29; the lattershaft extends upwardly through the upper plate 1 to aconsiderable distance and is designed to receive the tablet support for the record. Rigidlv secured to this mandrel shaft is a driving worm wheel 30, which meshes wit-h a worm on a worml shaft 31, which latter carries.. the usual governor 32. The shaft 31 is mounted in a suitable bracket hanger 33 secured-to the under face of the plate 1.

l* As a means for regulating the speed of the inotoi' through the governor, I provide the following mechanism. Upon the bracket 33, I secure a plate 34 providing the saine with a lateral extension 35. At the free end of said bracket extension I provide a threaded aperture to receive the governing screw 36. About midway of the length of the bracket ,extension 35, I provide a lateral bearing support 37, upon which is pivoted the brake lever 38. This brake lever is shown in detailin Fig. 5, a, Z) and c. At the upper end of the lever, as sh'own in said figure, there is an L-shaped projection 39, the free end of which is designed for contact with the inner face of the bracket eX- tension 35, while the vertical portion of said L-sha-ped extension is in .alinement with the inner end ofthe regulating screw 36,

so that as said screw is screwed back and forth the brake lever 38, being pivoted upon.

the bracket extension 37, may swing back and forth. Upon the free end of said brake lever 38, I provide a loop 40, to receive the brake felt 41, which bears upon the brake vdisk 42 of the governor as will be readily understood, and is usual in structures of this character.` As a meansfor yieldingly holding said brake felt away from the disk 42, Ir provide `the brake lever 38 with an upward and forward extending projection 43' in position to bear upon a fiat spring 44, which latter is secured by means ofthe screw 45 to the bracket 34, as clearly shown in Fig. 4. The tendency of such spring 45, is to swing-the brake lever 38 upon its pivot, away from the brake disk 42, and causing the opposite end to bear upon the governing screw 36. If, now, the governor screw 36 is screwed inwardly it will cause the brake lever to pivot with the brake felt 40, bearing upon the rotating disk 42. This braking mechanism may serve also to coins',

pletcly stop the motor if desired.

As a substitute for the usual pawl and ratchet mechanism upon the winding shaft, I substitute a well known equivalent in ythe form of a coil spring 46, closely embracing said shaft, having one end thereof carried upward and coiled through an aperture 47 in the end plate 7, as clearly shown in Figs. 1 and 3. The rotation of the shaft 15, by means of the usualfcrank, has a tendency to uncoil the spring and thus loosen its grip upon the surface of the shaft, thus permitting the free rotation thereof in one direction. 0f coui'se` the tendency of the driving spring in the spring barrel 16, is to rotate they shaft in the opposite direction, but the moment this tendency becomes effective the sprihng 46 hugs the shaft so closely as to effectually prevent rotation inthe direction opposite tothe usual winding.

F rom the above description, it will be seen that the winding shaft 15 and its 'gear 20. are carried by the bearing plate 7. The bearing extension 10 supports one end of the spring shaft 17. while the opposite end is supported by the' bearing support 6, 'so that when the screw 9 is removed and the .plate 7 swung into the dotted line position,

the gear 2O swings clear of the gear 19 and the spring barrels 16, together with the gear 1S, may be readily removed from the motor frame without disturbing any other element of the motor. v

In case a single spring barrel is desired, i

in place of a double spring barrel, \\such l spring barrel may be mounted upon a solid driving shaft of standard length to t the bearings 11 and 6. Of course ifa-plurality of spring barrels such as indicated irmy prior patent above referred to are desired, then the upper plate 1' may be extended and the hearing plate :7 secured to such eXtensio'n, for it will be. readily understood thatv a third or evrn a fourth spring mounted upon a correspondingly sectional shaft 17,

Would not change the location of the driving gear 18, lsince that is always located adjacent. lto the last spring barrel 1n the series.

From the above description it will be seen that I accomplish the object of my invention by means at once simple and thereby I am able to obviate some of the serious` difficulties in the use of talking machine motors.

I claim:

l'. In a springmotor, the combination of a motor frame, a driving shaft having. a spring barrel mounted thereon, means for detachabiy mounting said shaft andlspring barrel upon said frame comprising a bearing rigidly connected to said frame for carrying one end 'of said shaft, and a second bearing support pivotally mounted upon said frame -for 'supporting the other end of said shaft and means for rigidly securing said second bearing support to said frame.
